ABSTRACT
This study was carried out to compare the clinical effect of the endonasal lacrimal surgery done in 75 eyes of the 62 patients with that of the conventional lacrimal surgery done by the same operator in 72 eyes of the 57 patients. The diameter of intranasal ostium was 1.9 +/- 0.4 mm in endonasal approach and 2.6 +/- 1.4 mm in skin approach (p<0.05), respectively. Postoperative hospitalization were 1.7 - 2.5 days shorter in endonasal lacrimal surgery than those of conventional lacrimal surgery (p<0.001). Satisfactory tear drainge was observed in 29 eyes (90.6%) after endonasal dacryocystorhinostomy and in 28 eyes (90.3%) after conventional dacryocystorhinostomy, and 41 eyes (95.3%) revealed astisfactory tear drainge after endonasal conjunctivodacrystorhinostomy and 39 eyes (95.1%) showed good results after conventional conjunctivodacr yocystorhinostomy. In summary, endonasal lacrimal surgery showed no cutaneous scar, less edema and hematoma with short recovery time and similar success rate to the conventional lacrimal surgery. Thus, endonasal lacrimal surgery might be better than conventional lacrimal surgery.
